James Webb took pictures of two unusual galaxies

The new image of the galaxy pair uses data collected by Webb in infrared light and by Hubble in visible and ultraviolet light.

The James Webb Space Telescope took a picture of a pair of galaxies called VV 191, using some data from the aging Hubble Space Telescope. This was reported by Forbes.

It is noted that the image shows previously unseen details of a white elliptical galaxy (left) and a spiral galaxy (right). These two galaxies are relatively close, but not actively interacting.

These two galaxies were chosen out of thousands for their ability to help astronomers directly compare the properties of galactic dust. According to scientists, dust changes the brightness and color of galaxies, and therefore it is important to know about its nature and distribution. At the same time, dust is partially responsible for the formation of new stars and planets, so astronomers aim to determine their presence for further research.

In addition, experts with the help of a new image made an unexpected discovery.

In particular, the red arc seen in the upper left corner of the galaxy is an example of gravitational lensing. It occurs when the gravitational pull from a nearby but aligned galaxy biases and distorts the light from a distant star or galaxy, causing it to appear irregular and enlarged.

It was previously reported that Hubble, using the Advanced Camera for Surveys, took a picture of two interacting galaxies.
